Abstract
ABSTRACT
A circular saw includes a base with an opening therethrough, a blade guard coupled to the base, and a saw blade at least partially positioned within the blade guard and extending through the opening of the base. The saw blade and the blade guard are pivotable relative to the base to adjust a bevel angle of the saw blade relative to the base. The circular saw also includes a housing supported by the blade guard, a motor positioned within the housing that is operable to rotate the saw blade, and a bevel angle guide coupled between the base and the blade guard. The bevel angle guide configured to indicate the bevel angle at which the saw blade is adjusted. The bevel angle guide is integrally formed with the base as a single piece.

3. The circular saw of claim 2, wherein the saw blade is rotatable about a rotational axis, and wherein the bent edge is oriented parallel with the rotational axis.
4. The circular saw of claim 2, wherein the base includes a front end and an opposite, rear end relative to a cutting direction of the saw blade, and wherein the bent edge is proximate and parallel with the front end of the base.
5. The circular saw of claim 2, wherein the bent edge between the base and the bevel angle guide is formed by bending the bevel angle guide from a first orientation, in which the bevel angle guide is parallel or co-planar with the base, to a second orientation, in which the bevel angle guide is perpendicular to the base.
